Motor and Transmission Mount Set, Poly 75D (BMW E30 325)

Product Description

Motor and Transmission Mount Set, Poly 75D for BMW E30 323, 325. The stock motor and trans mounts deflect as torque moves through the drivetrain, allowing the motor and trans assembly to move. These straight bolt-through polyurethane mounts will eliminate virtually all of the movement of the engine and transmission under load – increasing power transfer to the rear wheels.

These extremely hard race-spec 75D durometer polyurethane motor and trans mounts are the hardest available (aside from solid aluminum) and the best option for race classes where solid mounts are not allowed, or for those who do not wish to deal with the issues that may arise when using solid mounts.

Our U.S. Military Spec 75D durometer compound is as hard as a bowling ball, yet has elasticity and memory. This exclusive compound allows us to manufacture a mount that has virtually the same performance as a solid mount without the harshness on the brackets/chassis associated with solid mounts. Likewise, its elasticity and memory means they are also free from deformation which plastic mounts (Delrin, UHMW) are very prone to.
